This invention relates to machines for use in the manufacture of shoes,and in some aspects more particularly to machines for lasting the toeends of welt shoes. The invention as herein illustrated is applied to apower operated toe lasting machine which, except as hereinafter noted,is constructed generally as disclosed in United States Letters PatentNo. 2,420,684, granted on May 20, 1947, on an application of C. A.Robinson.

The machine illustrated in the above-cited Letters Patent is a poweroperated toe lasting machine which is provided with toe embracing wipersfor wiping the marginal portion of the toe end of a welt shoe upperinwardly over the feather and against the rib of the insole, the machinealso being provided with automatic means for applying a wire binderabout the toe end of the shoe to hold the upper in lasted position, andmeans for vfastening the binder in place by staples driven through v themargin of the upper and the rib of the insole at the opposite sides ofthe shoe bottom. An object of this in,- yention is to provideimprovements in such binderapplying means better to adapt them foroperating on shoes of different sizes, and the invention is accordinglyherein shown as embodied in means forming part of the same generalorganization as disclosed in said Letters Patent.

For the purpose in View, the machine herein shown which has a pair ofgrippers for gripping the ends of a binder at opposite sides of theshoe, automatic means for feeding binder wire to these grippers andabout the toe end of the shoe, and operating means for closing andmoving the grippers lengthwise and widthwivse ofthe shoe to apply thebinder to the lasted shoe, is provided with novel means associated withthe gripper operating means adapted to vary the length of binder wireland the timing of the widthwise movement of the grippers according tothe size of shoe being operated upon. More particularly, as hereinillustrated, the variation in the length of binder wire is effected byvarying the time that the right-hand gripper closes on the binder wireduring the lengthwise advance of the grippers, the left-hand gripper'always closing at the same time early in the lengthwisemovement of thegrippers. That is, as the two grippers begin to move lengthwise of theshoe the left-hand gripper may grip the wire earlier than the right-handgripper and thus pull additional wire around the toe before theright-hand gripper closes. By delaying the closing of the right-handgripper for a longer time, the length of the binder wire pulled by theleft-hand gripper through the right-hand gripper may be increased.

In the machine to which the invention is herein shown as applied, thewipers, after wiping the marginal portion of the upper inwardly, arepartially retracted lengthwise and widthwise of the shoe and are alsoraised slightly to relieve their pressure on the upper, after which theyare again moved inwardly and are forced downwardly t9 apply the linalpressure. It is at the time when the wipers are thus partially retractedthat the binder, under the of operations of the machine.

force applied thereto by the grippers, is pulled fully inwardly againstthe upstanding margin of the upper. The wipers are supported on a wipercarrier which is first moved heightwise of the shoe to cause the wipersto wipe the upper in that direction, and it is at this time that thebinder wire is automatically fed and then measured to length by thegrippers. The upward movement of the wiper carrier causes the wirebinder to be severed from the wire supply and also causes a wireguideway which leads the binder from One gripper to the other around thetoe end of the shoe to be opened for application of the binder to theshoe.

To fasten the binder to the shoe, the machine to which the invention isherein shown as applied is provided with fastening-inserting mechanismssimilar to those disclosed in the aforementioned patent which formstaples of line wire and drive them into the margin of the'upper and therib of the insole in positions to straddle the binder at the oppositesides of the shoe bottom respectively in locations beyond the forwardend of the wipers. After fastening the ends of the binder thefastening-inserting mechanisms are automatically returned to startingposition and the final cycle of the machine returns all other parts ofthe machine to their starting positions for operation on another shoe.

The above features of the invention, including various novel details ofconstruction and combinations of parts, will now be more particularlydescribed with reference to the accompanying drawings and thereafterpointed out in the claims.

Such parts of the machine herein shown as are common to the disclosuresof prior Letters Patent, including the above-mentioned Letters PatentNo. 2,420,684, will be hereinafter described only in so far as isnecessary for an understanding of the invention. For positioning theshoe, bottom upward, both lengthwise and laterally the machine isprovided with a plate 2 (Fig. 13) having a downwardly extending flangeformed to engage the inner face `of the rib a of the insole around thetoe-end portion in the manner disclosed in Letters Patent No. 2,385,414,granted onr September 25, 1945, on an application of E. A. Holmgren. Asfurther therein disclosed, the shoe is positioned heightwise by threeinsole-engaging pins, one 0f which is shown at 4, the plate .2 beingmovable upwardly with the shoe until the pins engage `the insole inresponse to pressure applied to the shoe by an `upwardly movable toerest 6 at the beginning of the cycle At the beginning of the cycle-alsoa heel rest (not shown) is moved rearwardly into engagement with theheel end of the shoe to assist in holding it against lengthwisedisplacement.

For wiping the toe end of the upper into lasted position the machine hasa pair of wipers 10, Figs. 1 and 2, which are advanced lengthwise of theshoe and are closed inwardly widthwise of the shoe to embrace the upperabout the toe end of the last and are swung upwardly to wipe the upperheightwise of the last. After the heightwise wiping action, the wipersare further advanced and closed to wipe the marginal portion of theupper inwardly over the feather and against the rib of the insole, therib being supported against the inward pressure of the wipers by theplate 2. To assist in controlling the upper as it is wiped heightwise ofthe last the machine is provided with a retarder (not shown) whichclamps the marginal portion of the upper outspread on the wipers. Theconstruction of this retarder and of the means for operating andcontrolling it may be assumed to be substantially as disclosed inLetters Patent No. 2,380,407, granted on July 3l, 1945, on anapplication of the present inventor.

The wipers are detachably secured in slots in wiper holders 14 (Figs. 1and 2) which are supported on a wiper carrier 16 and are guided formovements about an axis extending heightwise of the shoe to close thewipers inwardly widthwise of the shoe. The wiper carrier 16 is supportedand operated by means constructed substantially as disclosed in LettersPatent No. 2,160,846, granted on lune 6, 1939 on an application of F. C.Eastman and A. F. Pym. Briefly, the carrier is supported near its frontend on a pair of links 18, only one of which is shown, and at its rearend on the upper end of a lever 20 pivotally mounted between its upperand lower ends on a rod 22, Fig. 2. The lever is pivotally connected atits upper end `to the carrier by a red 24. The links 18 are pivotallyconnected at their lower ends to arms 26, only one of which is shown,these arms being fast on a rockshaft 28 mounted in bearings in theframe. Also fast on this rockshaft is an arm 30 provided with a roll 32which lies in a cam track 34 formed in one side of a cam member (notshown) on a cam shaft 36. i Through this mechanism the wiper carrier 16is swung upwardly about the rod 24 to cause the wipers to wipe the upperheightwise of the last and is later swung downwardly `to increase thepressure of the wipers on the marginal portion of the upper over theinsole. To advance and retract the wiper carrier and the wiperslengthwise of the shoe, the lever 20 is swung about the rod 22 by a camtrack 38 formed in one side of a gear wheel (not shown) on the cam shaft36, the lever having thereon a roll 42 which lies in the cam track.

For operating the wiper holders 14 to close the wipers inwardlywidthwise of the shoe, there is mounted on the wiper carrier 16 (Figs. 1and 2) a slide 44 between which and the wiper holders there areyieldable connections 46 of the same construction as disclosed inLetters Patent No. 2,354,663, granted on August 1, 1944, on anotherapplication of the present inventor. The slide 44 is operated through arod 48 the front end portion of which is threaded therein, and byturning the rod the slide may be adjusted lengthwise of the shoerelatively to the wiper carrier 16 to adjust the wiper holders 14 andthe wipers toward or from each other. Operative movement is imparted tothe rod 48 through spring mechanism 56 by a pair of links 58 connectedto a bell-crank lever 60 mounted on a shaft 62 supported in a dependingportion of the wiper carrier 16, substantially as disclosed in greaterdetail in Letters Patent No. 2,160,846. The bellcrank lever 60 isconnected by a link 64 to an arm 66 fast on a rockshaft 68 on which isalso secured an arm 70 provided with a roll 72 lying in a cam track 74in the previously mentioned gear wheel (not shown). In the constructionherein shown the lever 60 is loosely mounted on the shaft 62.

As explained in Letters Patent No. 2,420,684, the

timing of the movements of the wipers 10 is such that after they havewiped the marginal portion of the upper inwardly over the insole theyare partially retracted lengthwise and widthwise of the shoe and areraised slightly to relieve their downward pressure on the upper, afterwhich they are again moved inwardly and are forced downwardly to applythe final pressure to the upper. At this point the cycle of operationsof the machine is automatically interrupted to permit a wire binder,applied to the toe as hereinafter described in proper time relation tothe above-mentioned movements of the wipers, to be fastened to the shoe.

For applying a wire binder about the toe end of a shoe to hold the upperin lasted position, the machine herein shown is provided with a pair ofgrippers 82, 82 (Fig. l) supported for movements widthwise of the shoeon the front end of two levers 84, 84 (Figs. 3 and 4). The levers aremounted to swing about bearings secured by screws 96 and nuts 98 todepending portions 92 of slides 88, 88. To cause the grippers to movelengthwise of the shoe, the slides 88 supporting the grippers throughthe levers 84 are mounted for lengthwise movement in guideways 106(Figs. 4 and 5) at opposite sides of the wiper carrier 16 and are movedforward yieldingly through springs 108 the forward ends of which aremounted in blocks 110 secured in recesses 114 of the slides 88 by pins112. The rearward end of each spring is contained in a bore 11.6 in aslide 118 mounted for lengthwise sliding movement in the recess 114 of.cach slide 88. For retaining the slide 118 in the recess, cach slide 8Sis provided with a key 122 which also lies in a slot 120 extendinglengthwise in each slide 1.18, the key also acting as a stop to limitthe relative movement of the slides 88 and 118 by contacting the forwardend of the slot 120. The left-hand slide 118 is connected by a link 124to an arm 126 (Fig. l) `while the righthand slide is connected by a link124 to one arm 129 of a bell-crank lever 128, both the arm 126 and thebell-crank lever being xed by pins to the shaft 62 freely rotatable inbearings in the wiper carrier. The other arm 130 (Fig. 2) of thebell-crank lever is connected by a link 132 to a cam lever 134 whichalso carries a roll 136 lying in a track 138 in one side of a cam 140fixed to the cam shaft 36. Through the connections described, the track138 acts in the proper time relationshiptto the lengthwise movement ofthe wiper carrier 16 to advance yieldingly the slides 88 and hence thcgrippcrs 82 carried by the levers 84.

To swing the grippers toward the shoe, cach lever 84 is provided with arearwardly extending arm 107, (Fig. 3) from which a tension spring 100extends to a depending portion 104 (Fig. 4) of one of the slides 88 tourge the front end of each lever 84 toward the shoe. Both levers,however, are held initially in outward positions away from the shoe byrolls 142 which are carried on pins 144 on the arms 102 and which lie intracks 150 in cam plates 148, 148 secured to the wiper carrier.l\'lounted on each roll between a shoulder on the roll and the surfaceof the arm carrying it is a compression spring 146 (Fig. 6) which holdsthe roll up against a surface 151 contiguous with the track 150 of theplate 148. As the levers 84 move forwardly with the slides 88 relativelyto the plates 148, the rolls 142 following the tracks 150 reach portions152 (Fig. 3) of the tracks which then allow the springs 100 to swing theforward end of both levers 84 and hence the grippers toward the shoe. Tovary the time that the grippers swing inwardly toward the shoe theplates 148 are adjustable lengthwise of the wiper carrier in a mannerhereinafter described. The grippers swing inwardly until the leadingedge of the grippers contact the upper of the shoe.

Each gripper 82 includes a bar 192 (Figs. 7 and 8) which is pivotallymounted at its outer end for swinging movements heightwise of the shoeabout a pin 193 secured in an upstarlding portion of a block 194 havinga threaded stud 196 secured in the frontend of one of the levers 84 by anut 198, the block being x'ed against swinging movements relative to theleverby a tongueand-groove connection. Secured to each bar 192 by ascrew 200 is an extension 202 having a downstanding `lip 203 whichserves as one of the jaws of the gripper. Mounted for sliding movementin a recess in the extension 202 is a slide 206 the inner'end of whichhas teeth thereon and serves as the other jaw of thev gripper. Arrangedto slide widthwise of the shoe on a' 'T-shaped section of the bar 192,Fig. 9J, is a slide 204 having a shelf portion 205 which cooperates withthe vlip 203 and the slide 206 to provide a passageway'208 through whichthe toe binder is fed as hereinafter described. By means hereinafterdescribed the wire is guided to move in a curved path below the wipersfrom the right-hand gripper to the left-hand gripper and to enter thespace between the jaws of the latter.

For positioning the inward en d of the grippers heightwise for propercontact with the shoe, each slide 204 is connected by a pin 300 to theenlarged slotted head of a downwardly extending rod 308 which hasmounted thereon two collars 309 and 310 (Fig. 7) and a spring 311compressed between the collars. The collars are mounted for heightwisemovements in alined bores 312 in two inwardly extending ears 314 of amember 316 which is mounted for heightwise adjustment on an adjustingscrew 320 rotatably secured to the front end of a lever 322, Fig. 5, bya shoulder screw 324 and nut 326. A shoulder on the collar 310 restos onthe upper surface of the lower ear 314 restraining the lowerend of thespring 311. The spring, bearing on the bottom of the collar 309, urgesthecollar and hence the rod 308 upwardly to a position limited byengagement of a shoulder on the collar 309 with the lower surface of theupper ear 314 and by engagement of a nut l313 on the lower end of therod with the bottom of the collar 310. Upward movement of the rod 308acting through the pin 300 swings the inner end of the gripperheightwise about the pin 193. The initial heightwise position of eachgripper, when positioned outwardly from the shoe, however, is determinedby an eccentrically adjustable stop 328 on each slide 204 and riding onan inwardly inclined cam surface 332 of an extension 334 of Aeach slideJ88. As the grippers are moved bodily toward the shoe bythe springs 100the stops 328 ride along their adjacent inclined surfaces 332 allowingthe springs 311 to swing the grippers heightwise until the shoulder onthe collars 309 contact the upper ears 314 and the nuts 313 contact thebottom of the collars 310. In this manner each gripper is held in theproper heightwise position for engaging the shoe but is capable ofindependent yielding movements up or down against the action of itsspring 311. To vary the heightwise position of the grippers in orderproperly to position the ends of the binder against the shoe, themembers 316 are adjustable heightwise by rotation of their adjustingscrews 320 against the resistance of a spring pressed plunger 327contained in each of the members 316. 'l

To provide motion for gripping the wire, each gripper slide 206 (Fig. 8)is provided with two downstanding lugs 297 which lie in a slot 298 Vofthe slide 204 and which embrace the pin 300 rotatably mounted in theslide 204 and in the head of the rod 308.. Each pin 300 has a tlatreduced portion 301 the purpose of which will hereinafter appear and atthe rearward side of the slide 204 the pin is provided with anupstanding arm 302 which engages a pin 304 extending from the rear faceof the slide 204 (Fig. 3). The forward end o f the pin 30,0 is providedwith a slot restraining one end of a Atorsion spring 306 (Fig. 7) whichrotates the pin clockwise, as viewed in Figs. 7 and 8, to aposition'limited by the engagement of the arm 302 with the pin 304.While in this position, as shown in Figs. 7 and 8, the pin 300 isembraced at its full diameter'by the lugs 297. Each lever 3,22 carryingone of the members 316 and hence` a pin 300 is mounted for swingingmovements toward the shoe about one of the bearings which' also sup'-ports one of the aforementioned levers 84 (Fig. 4). Each lever 322 has arearwardly extending arm 336 (Figs. 3 and 4) cooperating with and lyingin substantially the lsame plane as one of the arms 102 on a lever 84.Compression springs 338 with their ends contained in bores in the arms336 and 102 constantly urge these arms apart. The arms 102, however, areprevented from swinging movement about the bearings 90 by the rolls 142,carried by the arm, being restrained by the cam tracks of the cam plates148. The right-hand arm 336 is prevented from swinging movement awayfrom its cooperating arm 102 by a pin 340 depending from the right-handplate 148 engaging a surface 342 on the arm 336, while the lefthand arm336 is restrained from swinging movement by a pin 344 in the wipercarrier 16 engaging a surface 346 on the left-hand arm 336. The effectof the relative immobility of the arms 336 and 102 is to maintain theslides 206 away from the lips 203 of both grippers 82 (Fig. 8) so thebinder may be fed freely through the passages 208 in both grippers. Asthe slides 88, 88 move lengthwise relatively to the wiper carrier 16,being so moved by the action of the cam track 138 (Fig. 2), the pin 344(Fig. 3) carried by the wiper carrier loses contact with the surface 346of the left-hand arm 336 and rides along an angularly disposed surface348 allowing the spring 338 to swing the left-hand arm 336 away from itscooperating arm 102. As the arm 336 swings, the front end of theleft-hand lever 322 moves inwardly relatively to the left arm 84 causingthe pin 300 in the left-hand gripper to move the slide 206 inwardly,clamping the left-hand end of the binder wire against the lip 203 of theleft-hand gripper 82. Meanwhile the pin 340 (Fig. 3) carried by theright-hand plate 148 is still riding along the surface 342 oftheright-'hand arm 336 preventing the slide 206 of the right-handgripper from gripping the wire. Continued movement of the slides 88, 88causes the left-hand gripper'to pull the binder wire from a reel 268(Fig. 12) through the right-hand gripper and a wire guide 210 (Fig. 3).When the pin 340 carried by the right-hand plate 148 leaves the surface342 of the right-hand arm 336 and rides along a surface 350 angularlydisposed to the surface 342, the spring 338 swings the right-hand arm336 away from its associated arm 102 causing the right-hand arm 322acting through the member 316, rod 308 and pin 300 (Figs. 7 and 8) toclamp the slide 206 in the right-hand gripper against the binder, thusgripping the binder with the right-hand gripper. Further lengthwisemotion of the slides 88, 88 exerts an equal pull on both ends of thebinder by both grippers.

In a manner presently to be described the plates 148 may be adjustedlengthwise relatively to the wiper carrier to vary the timing of theclosing of the right-hand gripper. As the position of the plates 148 areadjusted the pin 340 carried by the right-hand plate is moved lengthwiserelatively to the position of the pin 344 carried by the wiper carrier16 varying the time lag between the closing of the left-hand gripper andthe right-hand gripper. By adjusting the plates 148, the length of timethat the left-hand gripper is allowed to pull binder wire through therighthand gripper before the latter grips the wire may be varied toobtain a longer or shorter binder depending on the size of shoe beingoperated upon.

` To vary the length of binder wire in the manner just described as wellas to vary the timing of the inward swing of the grippers for operatingon shoes of different sizes, the cam plates 148 are mounted forlengthwise movement relative to the wiper carrier 16 in recesses 154(Fig. 5) extending lengthwise at opposite sides of the carrier. Theplates 148 are retained in the recesses 154 by retainers 156 one ofwhich is shown in Fig. 5, secured in slots 158 in the carrier 16 byscrews 160 and lying in a groove 161 in each plate 148, the plates alsobeing supported on the upper surface of the arms 102.

Fastened to` inwardly extending lugs 162 (Fig. 3) at the rear of eachplate 148 by screws 164 is a member 166 extending laterally between theplates and having two rearwardly extending arms 168. Pivotally securedto the arms 16S by pins 17() are two blocks 172 lying in slots 174 (Fig.2) formed in two arms 176 which are joined together at their upper endsby a web and which are rotatably mounted on the aforementioned shaft 62journaled on part of the wiper carrier 16. A lug 178 (Fig. l) on theupper left portion of the arms 176 carries a freely rotatable pin 179which has an enlarged rectangular head having a vertically extendingbore receiving the end of a rod 180 (Fig. l). The rod 180 extendsforwardly through a bracket 182 fastened to a cover plate 183 on thewiper carrier 16 and through a hole in the plate and has threaded on itsforward end a block 184 in which there is a spring-pressed plunger 186having a knob 1.88. The plunger is arranged to be received in any one ofsix detent holes 190 in the cover plate 183. Through the connectionsdescribed, the carn plates 148 may bc adjusted lengthwise relative tothe wiper carrier 16 by moving the plunger 186 to any one of severaldetent holes 190. By setting the plunger 186 in one of the forwarddetent holes, the rolls 142 carried by the arms 102 must travel fartherbefore contacting the portion 152 of the cam track 15G in the plates148, thus delaying the inward swing of the grippers 82. Also, by thusadvancing the position of pin 340 relatively to pin 344, the closing ofthe righthand gripper is timed to provide a longer binder wire. Bysetting the plunger in the rearward detent holes, the binder wire willbe shorter and the grippers will swing inwardly toward the shoe at anearlier time.

Secured on the front end of the right-hand slide 88 (Fig. 3) is abracket 258 (Fig. 3) to which is fastened by a screw 260 a bar 262having a rearwardly extending portion 264 which serves as a wire-guidingnozzle in alinement with the passageway 208 in the right-hand gripper 82when the parts are in their initial positions. From this nozzle aflexible wire guide 266 leads to a wire-feeding mechanism shown in Fig.12. This mechanism is substantially similar to that disclosed in UnitedStates Letters Patent No. 2,638,610, granted on May 19, 1953, on anapplication filed in the name of the present inventor and will be hereindescribed only to the extent necessary for understanding of the presentinvention.

The supply of binder wire Wis supported on a reel 268 (Fig. 12)rotatably mounted on a bracket 270 which is secured to the right-handside of the machine frame. The wire from the reel passes between twofeed wheels 272 and 274 which are connected together by a gear wheel 276concentric with the feed wheel 272 and a gear wheel 278 concentric withthe feed wheel 274. The gear wheel 276 is fast on a shaft 280 mounted ina bearing in the bracket. The inner end of the shaft is connected bymeans of one-direction ratchet clutch, not shown, to a pinion 282 inengagement with the teeth of an upwardly and downwardly extending rackbar 284 the lower end of which is pivotally connected to a lug 286 (Fig.2) threaded into one end of a cam lever 288. The other end of the leveris provided with a roll 292 which rides on the periphery of thepreviously mentioned cam 140. Through the connections described, the cam140 acts early in the machine cycle to feed the wire by moving the rackbar 284 in an upward direction. A spring 294 extending between the frameof the machine and the lug 286 acts to return the rack bar 284 to itsdownward position, as in Fig. 2, when the roll 292 and cam 140 allowsuch motion. The downward return movement of the rack bar causes noreverse movement of the feed wheels 272, 274 due to the slipping actionof the one-direction clutch interposed between the pinion 280 and thefeed wheel 272. To prevent reverse movement of the feed wheels 272, 274the binder wire W is engaged frictionally by a brake member 296 (Fig.12) which is one arm of a bell-crank lever pivotally mounted on thebracket 270 and controlled by a spring 298. From the feed wheels 272,274 the wire is guided by the flexible wire guide 266 to the nozzlemember 264. To vary the length of the binder wire as previouslydescribed for operating on shoes of different sizes, the left-handgripper 32 is arranged to grip the wire before the right-hand gripper soas to pull wire from the reel 268 during the early portion of theforward movement of the grippers 82, the feed wheels 272, 274 movingfreely with the advance of the binder wire at that time due to theslippage of the one-direction clutch in the feeding mechanism. ln apredetermined time relation, adjustable in a manner previouslydescribed, the right-hand gripper grips the wire preventing any furtherpulling of the wire from the reel 268 by the left-hand gripper.

To direct the wire from the right-hand gripper to the left-hand gripperthere is provided a wire guide 210 which includes a substantiallyU-shaped member 212 having a rearward extension 214 (Fig. 11) secured bya screw 216 to a forward portion of the wiper carrier 16, see also Fig.3. The member 212 has therein a guideway 218 for the wire. Arrangednormally to close this guideway on the side toward the shoe is anothersubstantially U- shaped member 220 having an upwardly extending flange222 which lies in front of the guideway 218 when the member 220 is inits initial position. A downwardly extending arm 223 of the member 220is mounted to swing about n pin 224 secured in the extension 21.4 of themember 212. Pivotally connected to the lower end of the arm 223 is a rod226 extending rearwardly through a bore 228 in the wiper carrier. Aspring 230 on the rod 226 extending between a shoulder on the forwardend of the rod and the wiper carrier urges the arm 223 to swing in aclockwise direction as viewed in Fig. l1 to maintain the member 220 inposition to close the guideway in the member 212 when the wiper carrieris in its initial position, as shown in Figs. 2 and 11. Mounted forswinging movement on a depending portion 232 of the extension 214 on themember 212 is a link 234 connected to an arm 236 by means of a shoulderscrew 238 lying in a slot 240 in the lower end of the link 234. The arm236 is fulcrumed on a shaft 242 which turns in lugs on the frame of themachine. Extending upwardly from the arm 236 above its fulerum is acylindrical portion 244 having a bore 246 which receives a plunger 248.A spring 250 contained in a bore in the plunger 248 resting against thebottom of the bore 246 constantly urges the plunger in an upwarddirection. The upper end of the plunger 248 is formed to fit within aslot 252 cut in the lower surface of the wiper carrier 16 and to provideshoulders on the plunger which engage a surface 254 on the bottom of thecarrier. Threaded on the rearward end of the rod 226 is a block 256tting within the slot 252 in the wiper carrier, the block being arrangedto contact the plunger 248 at the proper time. It should be noted thatas the wiper carrier rises during its cycle of operation the plunger 248will be constantly held up against the surface 254 by the spring 250. Asthe link 234 moves upwardly with the wiper carrier the lower end of theslot 240 in the link contacts the screw 238 swinging the arm 236 and itsassociated plunger 248 clockwise, as viewed in Fig. 11, to engage theblock 256, as it moves forward with the wiper carrier, moving the blockrearwardly against the action of the spring 230 and causing the member220 to be displaced about its fulerum 224 from in front of the wireguideway 218 in t'he member 212.

Also in response to the upward movement of the wiper carrier 16,substantially at the end of that movement, the portion of the wire fedinto the wire guide 212 and into the grippers 82 to serve as a toebinder is severed from the rest of the wire by a cutter 354 (Fig. l0) ofwhich the cutting edge 356 is substantially contiguous to the rear faceof the wire guiding nozzle 264. The cutter extends outwardly along thebar 262 and is loosely mounted to swing about a pin 350 journaled in abore 352 (Fig. 3)'

armadas in the rear face of the bar. The cutter is constructed in such amanner that apair of springs 358 maintain the cutting edge 356 in closecontact with the wire guiding nozzle, the springs also serving to returnthe cutter to its initial position about the pin 350. The outer end 360of the cutter 354 is connected by a downwardly extending link 362 (Fig.l) to a rod 364 which extends downwardly through an eye 366 formed on apin supported for rotary movement in a bore 368 in a bracket 370 securedAto the frame of the machine. Fixed to the lower end of the rod 364 andspaced below the eye 366 is a collar 372 arranged to engage the lowerface of the eye upon upward movement of the rod. As the wiper carrier 16moves upward during the heightwise wiping cycle of the machine, theright-hand slide 88 moves up bodily with the carrier, carrying with itthe rod 364.` When the collar 372 contacts the eye 366 the cutter 354swings about the pin 350 causing the cutting edge 356 to shear thebinder wire.

In timed relation to the advancing and closing movements of the wipersto wipe the marginal portion of the upper inwardly over the feather andagainst the rib of the insole, the grippers 82 having previously grippedthe wire .binder are moved forwardly lengthwise of the shoe to pull thebinder out of the guideway 218, inwardly under the wipers and againstthe upstanding margin of the upper and are also moved inwardly widthwiseof the shoe to position the ends 0f the binder in proper position to befastened to the insole rib. The above-mentioned forward and inwardmovements of the grippers both result from the forward movements of theslides 88, 88 along their guideways 106 in the wiper carrier, theforward movements being effected directly by the movement of the slidesacting through the levers S4 and 322, and the inward movements beingeffected by the springs 100 and by the cam tracks 150 in the plates 148acting on the rolls 142 mounted on the arms 102 of the levers 84. At thecompletion of the lengthwise movement of the gripper operatingmechanism, the springs 108 are under compression resulting from movementof the bell-crank lever 128 and the arm 126.

When the wipers are at the limits of their first inward wiping movementsover the shoe, the binder may first be pulled only part way inward underthe wipers about the end of the toe by the action of the springs 108,the downward pressure of the wipers on the upper having been somewhatrelieved to permit this to be done. When the wipers are partiallyretracted prior to the second and final wiping operation, the binder ispulled farther inwardly against the upstanding margin of the upper byexpansion of the springs 108, and when the wipers are again movedinwardly and forced downwardly they press the binder rmly against theupper. The binder having thus been applied to the shoe and its oppositeend portions having been positioned against the upper beyond the forwardend of the wipers by the grippers 82, the cycle of operations of thewipers is interrupted with the wipers applying their full pressure tothe upper to permit the binder to be fastened to the shoe.

For fastening the binder to the shoe the machine is provided with a pairof fastening inserting mechanisms 376 one'of which is shown in Fig. 13.These mechanisms are in most respects like the corresponding units shownin LettersPatent No. 2,420,684 which may be referred to for anunderstanding of their mode of operation. It should be suflicient,however, for the purpose of the present invention briefly to describetheir structure and mode of operation.

Each fastener inserting mechanism comprises an anvil 378, throat 379,and staple forming and driving mechanism not shown. Attached to andmoving with the staple driving mechanism is an arm 380 the purpose ofwhich will presently appear. `lust before the cycle of operations of thewipers is interrupted, the operation of ,the fastener insertingmechanisms is automatically commenced. The anvils 378 move downwardlyand outwardly to engage the insole rib a while the throats 379 moveinwardly to engage the upper so that the rib, the margin of the upper,and the ends of the binder are clamped between the throats and theanvils. During the inward movement of the throats, the end portions ofthe binder, to be straddled and fastened by the staples, are positionedin proper relation to the staple guiding passageways in the throats in amanner fully disclosed in the above-mentioned Letters Patent. Meanwhile,the staples are formed and then driven over the ends of the binder andthrough the upstanding margin of the upper and the insole rib to beclinched against the anvils, in locations beyond the forward end of thewipers.

Before the fastener inserting units complete their staple drivingoperation the grippers 82 are caused to release the ends of the binderby the action of the arms 380 moving with the staple driving mechanismsswinging the aforementioned arms 302 of the grippers inwardly. Asprevously described, both slides 206 of the grippers S2 were movedinwardly to grip the ends of the binder by movement of the levers 322acting through the members 316, rods 308 and the pins 300. While thebinder was being gripped each gripper slide pin 300 was embraced at itsfull diameter by downstanding lugs 297 of each slide 206. By Contactwith the arms 380, the arms 302 on the rearward end of the pins 300 areswung clockwise, as viewed in Fig. 13, until the reduced portions 301 ofthe pins 300 are in line with the innermost of the lugs 297 of theslides 206. By such movement the lugs 297 are released from closeengagement with the pins 300 so that the slides 206 no longereffectively grip the ends of the binder. At this time the'levers 322 areprevented from moving the pins 300 any appreciable inward distance underthe urging of the springs 338 (Fig. 3) since a screw 382 threaded intoeach of the rearward arms 336 of the levers 322 (Fig. 3) riding in abore 384 of each arm v102 and having a head 386 engaging a surface 388on each arm 102 effectively limits the inward swing of each of thelevers 322.

' When the grippers 82 release the ends of the binder, the springs 108(Fig. 4) act on the slides 88 t0 move the grippers forwardly to clearthe ends of the binder. As the slides 88 move forward, the rolls 142(Fig. 6) on the arms 102 slide off the surfaces 151 of the tracks 150 inthe plates l148 and rise against surfaces 390 of these plates to engagecam tracks 394 (Fig. 3).

When the fastener-inserting units have completed their staple drivingoperation, and return to their inactive position, the machine clutch isautomatically actuated to cause the machine to complete its cycle ofoperations. During this part of the machine cycle the slides 88 andtheir associated levers 84 and 322 are moved rearwardly by the action ofthe cam track 138 (Fig. 2) and the grippers moving rearwardly ,with theslides 88 also are moved outwardly by the tracks 394 (Fig. 3) acting onthe rolls 142. Near the end of the return movement of the slides 88 thesurface 342 (Fig. 3) on the right-hand arm 336 contacts the pin 340 toopen the right-hand gripper and the surfrace 346 on the left-hand arm336 contacts the pin 344 to open the left-hand gripper.

The manner of the operation of the machine in so far as pertinent to thepresent invention will now be briefly summarized. The operator presentsa shoe to the machine in a position determined by engagement of theplate 2 with the inner face of the rib at the toe end of the insole andthen manually starts vthe cycle of operations of the machine.Substantially at the beginning of the cycle the toe rest 6 and the heelrest are moved into shoe supporting positions, the toe rest clamping theshoe upwardly against the pins 4. Early in the machine cycle the wipers10 are advanced and closed to bring their wiping edges into positionsfor wiping the upper around I the toey heightwise of the last, and theyare moved upwardly by upward swinging movement of the wiper carrier 16to cause them thus to act on the upper. After the upward movements ofthe wipers they are further advanced and closed to wipe the marginalportion of the upper inwardly over the feather and against the rib ofthe insole. The wipers are then partially retracted and opened and areraised slightly totrelease their downward pressure on the upper, afterwhich they are again moved inwardly to their fully advanced and closedpositions and are moved downwardly to increase the pressure. At thispoint the wiping cycle is automatically interrupted by a cam operatedclutch controlling means.

Early in the above-described portion of the machine cycle the wirefeeding mechanism is operated to feed the binder wire through theright-hand gripper 82, along the curved guideway 218 around the toe andthrough the left-hand gripper. Thereafter, during the upward movement ofthe wiper carrier 16, the left-hand gripper 82 is closed on the binderwire by the spring 338 when the surface 346 of the left-hand arm 336moves away from the pin 344. As the slides 88, being moved by the camtrack 138, move the grippers forwardly, the left-hand gripper pullsadditional wire through the still open righthand gripper. At apredetermined time, adjusted by changing the position of the plunger 186according to the size of the shoe being operated upon, the surface 342moves away from the pin 34() and the right-hand gripper closes on thebinder wire stopping the passage of the wire through the gripper. Inresponse to the continued upward movement of the wiper carrier thebinder is severed from the remainder of the wire by the cutter 354 andthe guideway 218 of the Wire is opened by the member 220. The gripperscontinue to be moved Forwardly by their operating mechanism to apply ayielding pull to the binder and are moved inwardly into engagement withthe sides of the shoe by springs 100 in response to the movement of therolls 142 in the tracks 150. During part of this motion of the grippers,the wipers are being operated to wipe the marginal portion ot the upperinwardly over the insole. At the completion of the movement of thegripper operating mechanism the springs S are under compressionresulting from movement of the bell-crank lever 128 and the arm 126. Thegrippers thus pull the binder first into a position between the wipersand the upper at the extreme end of the shoe bottom, and when the wipersare thereafter partially retracted and also raised as hereinabovedescribed, the grippers are operated by expansion of the springs 108 topull the binder farther inwardly under the wiper into engagement withthe upstanding margin of the upper, Immediately prior to theabove-mentioned interruption in thc cycle of operation of the wipers,the fastener inserting units 376 are automatically set into operation.The action of the units locates the ends of the binder and drivesstaples to fasten the ends of\the binder to the upstanding margin of theupper and the rib of the insole in positions beyond the forward end ofthe wipers.

Prior to completion of the staple driving operation of the fastenerinserting units the arms 380 moving with the staple driving mechanismengage the arms 302 on the gripper slide pins 300 to cause the grippersto open 'and release the binder. Upon release of the binder the grippersare moved forwardly to clear the ends of the binder by further expansionof the springs 108, it being understood that the binder at this time isheld firmly in place against the upper around the toe by the pressure ofthe wipers.

After driving the staples, the fastener inserting units return to theirstarting positions and automatically cause the machine to resume itscycle of operation and to return to starting position those parts whichhave not already been returned. During this part of the cycle, thegrippers 82 are moved rearwardly by the action of the cam track 138 andare moved outwardly by the action of the tracks 394 on the rolls 142.

While the machine herein shown is provided with means for applying toshoes binders made of wire, it is to be understood that in various novelaspects the invention is not limied to the use of binder material ofthat type.
